Both MI methods are performed using \(M=30\)  imputations, and Rubin's rules [1]}, [2]} are used to obtain estimates of association and standard errors. All analyses are conducted using Stata 14, [3]} where mi impute mlogit is used for standard MI, the community-contributed command uvis mlogit [4]} for calibrated-\(\delta \)  adjustment MI, and mi estimate: logit for performing the main analysis in the completed datasets and obtaining the final results using Rubin's rules.[1]}, [2]}
